I've been lately practicing on some gas tanks and having a lot of fun and experience... On this one, I've decided to freehand with colored drawing pencil (it's waterbased, didn't cause any problem with paint or clear coat), the basic design and proceed with any details needed. Used my cm-c+ and wicked detail black. and c2o. This is my favorite so far and here are some pics of the progress. Hope you enjoy it! And a little vid..
